Benefits of technology

[0005]One or more embodiment provides a display device capable of minimizing damage to a transistor and / or an emission layer in a pixel area.
[0028]As the crack prevention pattern covers the side surface of the first insulating layer in the valley area, the crack prevention pattern may reduce or effectively prevent cracks from propagating to the first and second pixel areas. Accordingly, damage to the transistor and / or the emission layer in the first and second pixel areas can be minimized.

Problems solved by technology

When an external force is applied to the display device, cracks may occur in the display device.
When cracks occur in a pixel area of the display device or when cracks propagate to the pixel area, a transistor and / or an emission layer disposed in the pixel area may be damaged.

Embodiment Construction

[0036]The invention now will be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments are shown. This invention may, however, be embodied in many different forms, and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout.

[0037]It will be understood that when an element is referred to as being related to another element such as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being related to another element such as being “directly on” another element, there are no intervening elements present.

[0038]It will be understood that, although the terms “first,”“second,”“third” e...

Abstract

A display device includes a substrate including a first pixel area, a second pixel area spaced apart from the first pixel area, and a valley area between the first pixel area and the second pixel area, a first insulating layer on the substrate and in both the first pixel area and the second pixel area, a penetration hole through the first insulating layer and corresponding to the valley area, the penetration hole exposing a side surface of the first insulating layer and an upper surface of the substrate to outside the first insulating layer, a crack prevention pattern which is in the penetration hole and covers the side surface of the first insulating layer, and a second insulating layer facing the first insulating layer with the crack prevention pattern therebetween, the second insulating layer in contact with the upper surface of the substrate at the penetration hole.

Description

[0001]This application claims priority to Korean Patent Application No. 10-2020-0129938, filed on Oct. 8, 2020, and all the benefits accruing therefrom under 35 U.S.C. §119, the content of which is hereby incorporated by reference for all purposes as if fully set forth herein.BACKGROUND(1) Field[0002]Implementations of the invention relate generally to a display device. More specifically, the invention relates to a display device capable of minimizing damage thereto.(2) Description of the Related Art[0003]Display devices used in computer monitors, televisions (“TVs”), and mobile phones include organic light emitting displays (“OLEDs”) that self-emit light and liquid crystal displays (“LCDs”) that use light generated by a separate light source.[0004]When an external force is applied to the display device, cracks may occur in the display device. When cracks occur in a pixel area of the display device or when cracks propagate to the pixel area, a transistor and / or an emission layer dis...
